Answer:
r = √3v/π
Step-by-step explanation:
in order to make r the subject of formulae from
v = 1/3πr²
multiply through by 3
3(v) = 3 ( πr²/3)
3v = πr²
divide both sides by π
3v/π =πr²/π
3v/π= r²
in order to make r stand out we would do that by squaring both sides
r = √3v/π

Answer:
the answer is 200
Step-by-step explanation:
We can write 1/10 of 200 in the form of equation as follows:
\frac{1}{10} * 200 = x
Where x represents that number we want to find.
so the answer is 20
Answer:
$2.72
Step-by-step explanation:
If the price decreased by 20%, the final price will be 100% - 20% = 80% of the inicial price.
So, we can write the ratio box:
Old value New value
Percent value: 100% 80%
Value: $3.40 X
Then we can solve with a rule of three:
100% -> $3.40
80% -> X
X = 0.8 * 3.4 = $2.72
